Abstract (en)
[origin: EP0288900A2] 1.1 CD retaining device and adaptor 2.1 Previous CD retaining devices in CD players or CD cartridges are adapted to a specific CD format. If CDs of smaller CD format are to be played, there is the risk of the CD slipping, preventing engagement of the centring means and centring. 2.2 The invention overcomes this by an insert disc, the outside diameter of which corresponds to the diameter of the enveloping circle of the retaining device, being inserted into the CD compartment of the CD player or the CD cartridge. The inside diameter is adapted to the outside diameter of the CD of smaller CD format, so that the CD can be placed in the insert disc. 2.3 The CD retaining device can be used for playing all CDs of various CD formats on one and the same CD player.
